<p align=center><b>Release 4.1: Application-specific logging and recovery</b></p>
<p>The application-specific logging and recovery tools and interfaces have
been reworked in the 4.1 release to make it simpler for applications to
use Berkeley DB to support their own logging and recovery of non-Berkeley DB
objects.  Specifically, the DB_ENV-&gt;set_recovery_init and
DB_ENV-&gt;set_tx_recover interfaces have been removed, replaced by
<a href="../../api_c/env_set_app_dispatch.html">DB_ENV-&gt;set_app_dispatch</a>.  Applications using either of the
removed interfaces should be updated to call
<a href="../../api_c/env_set_app_dispatch.html">DB_ENV-&gt;set_app_dispatch</a>.  For more information see
<a href="../../ref/apprec/intro.html">"Application-specific logging and
recovery"</a> and the <a href="../../api_c/env_set_app_dispatch.html">DB_ENV-&gt;set_app_dispatch</a> documentation.</p>
